The purpose of this clinical trial was to compare the use of a manual toothbrush plus water flosser to a manual toothbrush alone on clinical signs of inflammation.
Seventy-two subjects were randomized into two groups and completed this four-week, single-blind, parallel, clinical trial. Group 1 used a Waterpik®Water Flosser (WF) once daily and brushed with a manual toothbrush twice a day. Group 2 brushed twice a day with a manual toothbrush only (MT). Subjects in group 1 were provided written and verbal instructions for the water flosser and all participants used the toothpaste and manual brush provided, brushing as they normally do. Data were evaluated at baseline (BSL), two weeks (W2), and four weeks (W4) for bleeding on probing (BOP), Modified Gingival Index (MGI), and Rustogi Modification of the Navy Plaque Index (RMNPI).
Both groups showed a significant reduction from BSL for BOP, MGI, and RMNPI at W2 and W4, except for MT W2 facial proximal MGI (p = 0.153) and marginal RMNPI (p = 0.324). The WF was significantly more effective than the MT for reducing BOP, MGI, and RMNPI at W2 and W4 for all areas measured. The WF was 3.13 times as effective for reducing BOP, 2.69 times for MGI, and 2.44 times for RMNPI at W4 (p < 0.001) for whole mouth scores.
The addition of the Waterpik®Water Flosser to manual tooth brushing is significantly more effective for improving gingival health than manual tooth brushing alone.
本临床试验的目的是比较使用手动牙刷加牙线冲洗器与单独使用手动牙刷对炎症临床体征的影响。
72名受试者被随机分为两组，完成了这项为期四周的单盲、平行临床试验。第一组每天使用一次Waterpik®牙线冲洗器（WF），每天用手动牙刷刷牙两次。第二组仅每天用手动牙刷刷牙两次（MT）。第一组的受试者收到了关于牙线冲洗器的书面和口头说明，所有参与者使用提供的牙膏和手动牙刷，按平常方式刷牙。在基线（BSL）、两周（W2）和四周（W4）时评估探诊出血（BOP）、改良牙龈指数（MGI）和海军菌斑指数的Rustogi改良版（RMNPI）数据。
两组在W2和W4时BOP、MGI和RMNPI相对于BSL均有显著降低，但MT组W2时面部近中MGI（p = 0.153）和边缘RMNPI（p = 0.324）除外。在W2和W4时，对于所有测量区域，WF在降低BOP、MGI和RMNPI方面明显比MT更有效。在W4时，对于全口评分，WF降低BOP的效果是MT的3.13倍，降低MGI的效果是MT的2.69倍，降低RMNPI的效果是MT的2.44倍（p < 0.001）。
与单独使用手动牙刷相比，在手动刷牙的基础上添加Waterpik®牙线冲洗器对改善牙龈健康明显更有效。
